The symmetric/asymmetric cholesterol- decorated dicyanodistyrylbenzene were prepared and the influence of symmetric/asymmetric structure on circularly polarized luminescence (CPL) properties was investigated for the first time. Both of them exhibited excellent fluorescence in solution and aggregated states. Their chiroptical properties were influenced greatly by the order degree of molecular stacking in different states. The symmetric structure with two chiral units was favorable for better CPL emission than asymmetric structure with one chiral unit. The highest g lum value was 1.5 × 10 −2 based on the effective chiral transfer and amplification of orderly liquid-crystalline molecular stacking of symmetric cholesterol-decorated dicyanodistyrylbenzene in mesophase.

In this paper, two acceptor-donor-acceptor (A-D-A) type organic small molecules, 4,4'-(5,5'-(benzo[c] [1,2,5]thiadiazole-4,7-diyl)bis(3-hexylthiophene-5,2-diyl))bis(N-(4-nitrophenyl)-N-phenylaniline) (NTPA 2 TBT) and 4,4'-(5,6-difluorobenzo[c] [1,2,5]thiadiazole-4,7-diyl)bis(N-(4-nitrophenyl)-N-phenylaniline) (NTPA 2 BTF 2 ), were synthesized and fabricated into resistive random access memory devices. Compared with our previously reported molecule NTPA 2 BT, NTPA 2 TBT has 3-hexylthiophene linkages bridging its donor and acceptor, while there are two additional fluorine atoms in the benzothiadiazole moiety for NTPA 2 BTF 2. Both the fabricated memory devices based on these two new molecules perform nonvolatile ternary memory characteristics with lower threshold voltages , higher reproducibility and better stability. The addition of 3-hexylthiophene bridges significantly promotes the planarity of the conjugation backbone and facilitates the molecular stacking, while the substitution hydrogen by fluorine improves the intermolecular interaction , and thus also induces an ordered molecular stacking. The insertion of 3-hexylthiophene bridges or fluorine atoms could be an effective strategy of tailoring organic molecules to improve data storage performance with lower power consumption.

To enhance synergistic therapeutic efficiency of tumor photothermal–thermodynamic–chemotherapy and address challenges of limited laser penetration, uneven heating, and poor temporal coordination among therapeutic modalities, we fabricated a photomicroneedle (PMN) system consisting of an optical fiber integrated into a perforated stainless-steel microneedle, in which the laser delivered via the PMN is emitted both from the tip and the sidewalls, enabling uniform intratumoral irradiation. The PMN-assisted tumor continuous high-intensity photothermal–thermodynamic alternate cycle therapy and chemotherapy strategy that consistently keeps over 90% tumor cell death within 48 h was developed. To implement this strategy, dual-layer nanocomposites were engineered by self-assembling IR825 and doxorubicin (DOX) into core nanoparticles (Dp825 NPs), which were then encapsulated in polydopamine (PDA)–Fe(III)–folic acid (FA) infinite coordination polymer (ICP) shell loaded with artesunate (ARS), forming nanocomposites (Dp825:ARS@PDA–Fe(III)–FA ICP NCPs). The resulting nanocomposites have high drug loading and tumor targeting efficiency, enabling precise spatiotemporal control of drug release to meet the requirements of the above coordinated strategy. In vivo studies demonstrated complete eradication of large tumors (∼300 mm3) without recurrence over 60 days, using only 300 mW·cm–2 laser power and a total injection dose of 5.0 mg·kg–1, which offers a promising platform for highly effective and minimally side-effect tumor therapy.

The photovoltaic performance and stability of scalable organic solar cells (OSCs) are significantly governed by the micromorphology, molecular interactions, and stacking behavior of the active layer. As the device area increases, these effects are amplified, making long-range morphological control of small-molecule acceptors challenging and frequently leading to performance degradation. Herein, a non-contact and size-insensitive magnetic-field-assisted printing strategy is developed, which modulates the chemical environment of molecular end groups during film formation and enhances intermolecular interactions, thereby regulating the molecular stacking behavior. These collectively improve the film homogeneity, reduce the defect density, and minimize the performance loss in large-area devices. Finally, the optimal pseudo-planar heterojunction OSCs, fabricated via air atmosphere printing, achieve a champion power conversion efficiency (PCE) of 20.23%. Furthermore, large-area binary modules with an aperture area of 25.00 cm 2 retain an optimized PCE of 16.70%, underscoring their strong potential for scalable production. Overall, this work proposes a universal approach for printing high-quality photoactive films and provides a valuable framework for the collaborative optimization of organic electronic devices.
